Fuzz Button Technology Providing Internconnect Solutions for Quantum Computing Systems

Quantum computing technology has the potential to trigger a new industrial revolution, thanks to its exponentially powerful computation capabilities.  The development of large-scale quantum computers requires critical components for high-frequency signal transmission, namely interconnects and interposers.

Overcoming Challenges in RCS Measurements using a High Order Basis Function Method of Moments Technique

Characterizing Radar Cross Section (RCS) is no easy task. Most ranges use low back-scattering pylons that require a low RCS target to hide the top edge of the pylon to measure the effect of the support. This article explores the idea of using a numerical technique as an effective alternative. 

Overcoming Size Limitations - the RF Performance Impace of Segmentation and Assembly on 3D Printed Luneburg Lenses

Segmentation is a powerful tool in extending the capabilities of otherwise workpiece size or workspace limited Additive Manufacturing technologies, and can enable the fabrication of complex dielectric structures. This is especially critical for highly intricate dielectric structures, such as metastructures, and Luneburg/GRIN RF lenses greater than 4.5” in diameter. 

5G NR Challenges & Trends in RFFE Design

The proposed capability enhancements from 4G long-term evolution (LTE) to 5G new radio (5G NR) were a massive leap designed to boost mobile telecommunications applications and enable many more. Aside from significantly boosting all major performance metrics, the 4G to 5G transition also heralds a more flexible and capable radio architecture with additional millimeter-wave frequency spectrum on top of legacy 4G LTE-Advanced (LTE-A) and new sub-6 GHz frequency bands. 

OTA Characterization of Phased Array Antennas and Antenna in Package (AiP)

This document looks at how Feko—in conjunction with Altair’s solutions for design simulation, exploration and optimization, structural assessment, and thermal analysis—can help antenna designers develop and verify their antenna solutions quickly, accurately, and efficiently. It will focus on how to realize automated, iterative design optimization through modelling and visualization.

Millimeter Wave Design: Optimizing Performance in RF Compression Mount Connectors

In millimeter wave designs, compression mount connectors can be used to avoid problems commonly associated with solder variations. However, when using compression mount connectors, the potential impact of pin compression and/or misalignment on electrical performance at high frequencies should be considered. Using modeled and measured data, this white paper investigates how misalignment and pin compression could impact a real-world design. It also explains how to detect and avoid issues in order to optimize performance and complete a successful design.
